INDIAN MARINE SURVEYS. 31 



The Andarnanese were found to be no longer treacherous nor 

 hostile to Europeans landing on their islands. A great number of 

 them now talk Hindostani, which they learn with great quickness. 

 A tide-watching party placed in tents at the west end of Andaman 

 strait was met by some 30 natives, who left their hut a mile and 

 a half distant and encamped close to the Englishmen, It was at 

 first supposed that they had come for protection against other 

 tribes, but it transpired that they had really come to protect our 

 people, a welcome change of feeling which is attributable to the 

 excellent administration of Colonel Caclell and his predecessors. 



During 1887, Lieutenant Helby, R.N., who had been in 

 charge of No. 1 Boat party, brought the survey of Beypur and 

 Calicut to a close in time to recess at Poona in May. Thirty miles 

 of the Malabar coast were well surveyed and the Calicut reefs 

 clearly depicted. Lieutenant Helby then handed charge of the 

 boat party to Lieutenant M. H. Smyth, R.N., who, during 1887-88, 

 made large scale surveys of the small ports of Porbandar and 

 Navibandar in Kathiawar, and also surveyed Cannanur on the 

 Malabar coast, all in excellent style. 



In 1887 Staff Commander T. C. Pascoe, R.N., left the Indian 

 Marine Survey and reverted to Admiralty employment after having 

 been 11 years in the Department, during which he had clone much 

 valuable work. 



A detailed report on the results of the deep-sea dredging casts, 

 by Surgeon-Naturalist Gr. M. Griles, is annexed to the Marine Survey 

 Report for 1887-8, as well as a tabular analytical catalogue of the 

 collection by Mr. J. Wood-Mason, Superintendent of the Indian 

 Museum at Calcutta. Another appendix is the interesting little 

 paper referred to above by Commander Carpenter, R.N., on the 

 mean temperature of the deep water of the Bay of Bengal, with its 

 accompanying chart, the general effect of which is to show how 

 rapid the fall in temperature is at the varying depths from the 

 surface down to 150 fathoms, while after 1,200 fathoms the change 

 in temperature becomes very slow. 



In 1889 Surgeon A. Alcock (who had succeeded to the post of 

 naturalist), I.M.S., was permitted to reside at Calcutta during the 

 recess, for the purpose of arranging the collections made and 

 deposited in the Indian Museum at Calcutta. Thanks to this per- 

 mission, Surgeon Alcock has been able to make a very large addition
